Diagnostic Sensitivity of Unenhanced CT for Cerebral Venous Thrombosis: Can Clot Density Measurement Replace CT Venogram?

 Cerebral venous sinus thrombosis is an important cause of stroke in young adults. Noncontrast-enhanced CT head (NECT) is almost always the first investigation. Our objectives were as follows: 1.

Extreme local recycling of moisture via wetlands and forests in North-East Indian subcontinent: a Mini-Amazon.

Moisture recycling in precipitation is an important hydrological process, accounting for ~ 67% globally. North-east India, home to the world's wettest place, boasts vast wetlands and forest-cover. Despite its proximity to the coast, we find locally recycled moisture to be the primary annual source of rainfall (~ 45%).

New insights into diffusive kinetic fractionation during liquid condensation under supersaturated environment: an alternative approach for isotope tagging of ground-level water vapour.

Stable water isotopes in ground-level vapour are key to estimating water exchange between geospheres. Their sampling, however, is limited to laser-absorption spectrometers and satellite observations, having inherent shortcomings. This study investigates diffusive kinetic fractionation during liquid condensation under supersaturated environment, providing a cost-effective, reliable way of sampling ground-level vapour isotopes (O, H).

Programmable electronic synapse and nonvolatile resistive switches using MoS quantum dots.

Brain-inspired computation that mimics the coordinated functioning of neural networks through multitudes of synaptic connections is deemed to be the future of computation to overcome the classical von Neumann bottleneck. The future artificial intelligence circuits require scalable electronic synapse (e-synapses) with very high bit densities and operational speeds. In this respect, nanostructures of two-dimensional materials serve the purpose and offer the scalability of the devices in lateral and vertical dimensions.

Thinking beyond hernia: a review of non-hernia groin lumps.

With increasing reliance on imaging, a large number of patients presenting with a groin lump are being referred to radiology to confirm the diagnosis of hernia, usually with an ultrasound in the first instance (occasionally MRI or CT). However, when imaging of the groin was performed, we have encountered many different kinds of non-hernia lesions in our practice. Such lesions can be categorized based on their tissue of origin and pathology.

Central Metatarsalgia and Walking on Pebbles: Beyond Morton Neuroma.

Objective: Central metatarsalgia relates to abnormalities of the second, third, and fourth metatarsals and their respective metatarsophalangeal joints. A variety of disorders present with central forefoot pain; they range from traumatic lesions (acute or chronic repetitive), inflammatory and infective disorders, nonneoplastic soft-tissue lesions, and benign tumors to malignant lesions. Patients often present with symptoms of localized pain in the forefoot that worsens on weight bearing (walking or running), which can be sharp or dull and often is perceived as a lump felt inside or underneath the foot and described as walking on a marble or pebbles.

Non-small cell lung carcinoma metastasis to the anus.

A 70-year-old man presenting with a lung mass was investigated and treated with pneumonectomy for adenocarcinoma of the lung. He re-presented 3 months later with a large perianal abscess and mass. Subsequent investigations and biopsies showed disseminated metastases from the lung primary.

Lumps and bumps around the foot and ankle: an assessment of frequency with ultrasound and MRI.

Benign and malignant tumours and tumour-like conditions frequently present as lumps in the foot and ankle. Although definitive histological diagnosis cannot be ascertained short of a biopsy, most entities can be confidently characterised on ultrasound and/or MRI. Masses in the foot and ankle present with lump, pain, paraesthesia, restricted mobility or a combination of these.
